Customer enrollment process for reference:
1. Customer calls Xcel Energy at 800.895.4999 so we can help determine which rate plan will work best.
2. If a fast charger is being installed, customer contacts builders.call.line@xcelenergy.com to check the load increase.
3. Customer contacts an electrician (you) for an estimate on the meter housing equipment installation.
4. When the meter housing is installed, inspected and energized, customer visits xcelenergy.com/EVRates and
completes the application form.
5. Customer sends the completed inspection document to builders.call.line@xcelenergy.com.
6. We’ll visit the customer’s home and install an off-peak meter next to the existing meter.

Customer installs:
• EV Billing Meter

Service Connection Options
Quick Reference Guide for Service Connection:
1. Choose a service connection option.
2. Contact the Builder’s Call Line at 800.628.2121 to schedule a line drop and reconnect. If there is a large load increase,
speak with a designer to determine if the service entrance conduit is still valid.
a. Duplex meter sockets require a simple disconnect and reconnect.
b. Overhead service requires a splice in the conductor past the weather head, which is made by Xcel Energy.
Customers need to provide an adequate length of wire to make this connection.
c. Underground service requires a connection in the wire below the meter sockets, in the same location that the
conduit entered the meter socket. Customers need to supply the junction and route conductor from the point of
delivery to the two individual meter sockets. The junction box requires a sealable hasp.
3. Customer visits xcelenergy.com/EVRates and completes the application form, and sends a completed inspection form
to the Builder’s Call Line, builders.call.line@xcelenergy.com.

Installation FAQs
Where do I install the meter socket and service box?
The second meter socket or duplex meter socket must be installed outside and grouped by the existing meter socket at a vertical
height of 4’–6’, measured from final grade to the center of the meter. The minimum horizontal dimensions of the platform shall
meet the National Electrical Code® requirements for working space, as specified under “Meter Clearances” in the Standards
for Electric Installation and Use manual. Additionally, clearances around the gas meter should be met. Refer to the following
diagrams and Drawing CR-10, in that publication for reference.
1. Area within dashed lines shall be clear of all obstructions.
2. 18” clearance shall be maintained to either side of the center line of the meter socket per NEC.
3. 36”, 42” or 48” clearance shall be maintained in front of meter socket per NEC.
4. Height of working clearance shall be per NEC.
5. The meter socket must be located within 2’ of the existing meter.
Does it have to be a duplex meter socket?
No. For new construction, a duplex meter socket may be a good option. But, it is not required on an existing premises. If two
separate sockets are being used, they should be next to each other with the two masts for an overhead service as close to each
other as possible. The second meter socket should be vertically aligned, (from the center point) with the existing socket and
within 24” horizontally, from the main house meter.
Installation FAQs
Can I install this as a sub-meter?
No. Industry best practice for safety is a dedicated service.
Is a lever bypass meter socket required?
Yes. The meter socket for the EV must be a lever bypass from a manufacturer on our approved list. It must also conform to all
other standards as depicted in section 4.13 from our Standard for Electrical Installation and Use.
What voltage charging equipment can I install for the EV rate?
EV chargers that use 120V, 240V or 208V (network) are all allowed. Available voltage will be dependent on
existing distribution facilities in the area.
Can I install the meter socket on a detached garage?
There are two options for customers wishing to charge their vehicle in a detached garage:
1. The customer may participate in the EV rate by installing the EV meter within 2’ of the existing meter. If the main house
meter is not on the garage, a line can be run to the detached garage.
2. The customer may participate in the Time of Day rate instead of the EV rate, and install a Time of Day meter on the
detached garage. In this case, the panel can be used for additional charges besides an electric vehicle. A second
service would need to be requested and started at an extra cost to the customer.
Can I install a fast charger?
Yes. Prior to installing a DC fast charger or an AC Level 2 charger, please call the Builder’s Call Line at 800.628.2121 to check
if a significant load increase will necessitate a service upgrade. With prior notification, we can make the necessary system
modifications to continue to reliably serve the EV customer and surrounding community.
Who do I call at Xcel Energy to confirm the meter specifications?
